William, I wasn't sure where your (usually) straightforward statements ended and tongue-in-cheek started, either. Re Google, I know what you mean: it's getting harder and harder to find good basic info instead of commercial/sales info. But that result was predicted when the Internet became commercialized.
Ann, it was not completely clear when things turned, so you did a good one on me. About Google; I have had quite a bit of serious frustration when attempting to find information about some product or system and the dumb google search instead turns up a hundred sites that want to sell me one, even if they don't have it and have no concept of what it is. At that point it becomes a first rate time waster.
But on the other topic, while invisibility in the normal sense is a big challenge, being un-noticed is a lot simpler, hence the comment about the missile launching dolphin and such. Consider how easy it would be for you to pass somebody by if a whole crowd were wearing AnnThryft masks. Spotting the real one is a challenge if they all look similar.
Ann, OK, that makes sense. Of course a missile launching fish would be a very interesting creature. Probably we could train a school of dolphin to escort a missile launching robot dolphin, giving it a nearly perfect cover. The main hazard would be poachers. Perhaps DARPA would be interested in that concept, which just popped into my head. I am not at all familiar with the DARPA dolphin program and have never heard of "Freddy the Fish".
Using a 3D printer, CNC router, and existing powertrain components, a team of engineers is building an electric car from scratch on the floor of the International Manufacturing Technology Show in Chicago this week.
In November, a European space probe will try to land on the surface of a comet moving at about 84,000 mph and rotating with a period of 12.7 hours. Many factors make positioning the probe for the landing an engineering challenge.
NinjaFlex flexible 3D printing filament made from thermoplastic elastomers is available in a growing assortment of colors, most recently gold and silver. It's flexible and harder than you'd expect: around 85A (Shore A).
